User’s Manual
Intel Pentium 4 Socket478 Processor Thermal Solutions
As processor technology pushes to faster speeds and higher performance, thermal
management becomes increasingly crucial when building computer systems. Maintaining
the proper thermal environment is key to reliable, long-term system operation. The overall
goal in providing the proper thermal environment is keeping the processor below its
specified maximum case temperature. Heatsinks induce improved processor heat dissipation
through increased surface area and concentrated airflow from attached fans. In addition,
interface materials allow effective transfers of heat from the processor to the heatsink. For
optimum heat transfer, Intel recommends the use of thermal grease and mounting clips to
attach the heatsink to the processor.
When selecting a thermal solution for your system, please refer to the website below for
collection of heatsinks evaluated and recommended by Intel for use with Intel processors.
Note, those heatsinks are recommended for maintaining the specified Maximum T case
requirement. In addition, this collection is not intended to be a comprehensive listing of all
heatsinks that support Intel processors.

Introduction of PT88AS/PT8AS Motherboard
Thank you for purchasing the PT88AS which provide extremely performance and
meet future specification demand.
PT88AS/PT8AS series motherboards are adopted with advanced technologies to deliver the
extremely performance for Intel Pentium 4 Northwood/ Hyper-Threading/ Prescott socket 478
processors. The motherboard also feature AGP 8X, Serial ATA RAID0, 1, USB 2.0 as well as
6-channel audio which are based on the advanced VIA PT880/PT800 chipset with FSB 800MHz
and DDR400 Memory clock support. The PT88AS also supports Dual channel DDR400 Memory
clock. Now we could know more details by reading the features of motherboards below.
1-1 Feature of motherboard
PT88AS/PT8AS motherboard is designed for Intel Pentium 4 Socket-478 400MHz/ 533MHz/
800MHz Front Side Bus Frequency CPUs and the memory size expandable to 2.0GB.
By using VIA PT880/PT800 chipset which provides 800/533/400MHz Front Side Bus frequency
and Dual channel DDR266/333/400 SDRAM (Dual channel function only for PT88AS)
support as a obvious further step to the next generation of 400/533/800MHz processors. These
motherboards also offered ULTRA ATA 133 and Serial ATA RAID 0, 1 functions to provide
speedier HDD throughout that boosts overall system performance.
Integrated AC’97 CODEC audio on system supports 6-channel speaker for 3D Surround Effect
which is fully compatible with Sound Blaster Pro® that gives you the best sound quality and
compatibility. AGP 8X slot enables more complex models and detailed textures with AGP 8X
graphic accelerators which creates richer and more lifelike virtual environments. The PT88AS/
PT8AS used VIA VT6103 LAN PHY supports 10/100Mbps data transfer rate full duplex, half
duplex operation. USB control as well as capability of expanding to 8 USB function ports
support USB2.0/1.1 Devices.
Built-in hardware monitor function will monitor and protect your computer which is the special
design in hardware for protecting Pentium 4 CPU from burned, and will shutdown power supply
automatically when CPU is overheated or the CPU cooling fan is not working.
Minor adjustable DDR memory 2.5V Voltage, AGP 1.5V Voltage, and other special functions
allows user to increase CPU Host clock step by step by setting up BIOS to approach over
clocking and increasing stability of the system.

2-3-2 About INTEL PENTIUM 4 478-PIN CPU
This motherboard provides a 478-pin surface mount, Zero Insertion Force (ZIF) socket, referred to
as the mPGA478B socket supports Intel Pentium 4 processor in the 478 Pin package utilizes
Flip-Chip Pin Grid Array (FC-PGA2) package technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent
overheating. If this is not the case, then purchase a correct cooling FAN before you turn on your
system.
WARNING!
Be sure that there is sufficient air circulation across the processor’s heatsink
and CPU cooling FAN is working correctly, otherwise it may cause the
processor and motherboard overheat and damage, you may install an auxiliary
cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. To locate the ZIF socket and
open it by first pulling the level sideways away from the socket then upward to 90-degree. Insert
the CPU with the correct orientation as shown below. The notched corner should point toward
the end of the level. Because the CPU has a corner pin for two of the four corners, the CPU will
only fit in the orientation as shown.
mPGA478B
Colden Arrow
CPU ZIF mPGAB Socket
When you put the CPU into the ZIF socket. No force needed to insert of the CPU, then press the
level to Locate position slightly without any extra force.

2-4 To install the system memory
This motherboard provides two 184-pin DUAL INLINE MEMORY MODULES (DIMM) sites
for memory ex pans ion avail able from min imu m memor y si ze o f 64M B to ma ximu m memor y si ze
of 2.0GB DDR SDRAM.

For Dual channel Limited!
1. Dual channel function only supports when 2 DIMM Modules plug in either both DIMM1 &
DIMM2. Only PT88AS supports this function.
2. DIMM1 & D IMM2 must be the same type, same size, same frequency for dual channel function.
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer to figure 2-4
to see what a 184-Pin DDR266/DDR333/DDR400 DDR SDRAM module looks like.
DIMM2 (BANK2+BANK3)

Figure 2-4
DIMM1 & DIMM2: Dual Channel 1
NOTE! When you install DIMM module fully into the DIMM socket the eject tab should be
locked into the DIMM module very firmly and fit into its indention on both sides.
WARNING! For the DDR SDRAM CLOCK is set at 200MHz, use only DDR400-compliant DDR
Modules. When this motherboard operate at 200Mhz, most system will not even boot if
non-compliant modules are used because of the strict timing issues, if your SDR Modules
are not DDR266-compliant, set the DDR SDRAM clock to 133MHz to ensure system
stability.
10
2-5 To install the Expansion Cards
WARNING!
Turn off your power when adding or removing expansion cards or other system
components. Failure to do so may cause severe damage to both your
motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. To read documentations or manuals for your expansion cards and make any necessary
hardware or software settings for your expansion card such as jumpers.
2. To remove your computer’s cover and the bracket plate on the slot you intend to use.
3. To align the card’s connectors and press firmly.
4. To secure the card on the slot with the screen you remove above.
5. To replace the computer system’s cover.
6. To set up the BIOS if it’s necessary.
7. To install the necessary software drivers for your expansion cards.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need to assign an IRQ address to operate. Generally speaking, an IRQ
address must exclusively assign to one use only. With standard factory design, there are 16 IRQs
available, but most of them are already in use.
Standard Interrupt Assignments
IRQ Priority Standard function
0 N/A System Timer
1 N/A Keyboard Controller
2 N/A Programmable Interrupt
3 * 8 Communications Port (COM2)
4 * 9 Communications Port (COM1)
